The Front Side
Marker light bulb is located at the amber colored lower outer edge of
the headlight assembly near the front quarter panel. (This bulb can be
difficult to remove for people with larger hands.)

Reach in to the engine bay and rotate the small
black plastic side marker bulb socket 1/4 turn counter clockwise before
pulling it straight out of the assembly.

Pull the old # 2825bulb straight out of the
socket and push in a new 2825 or other miniature wedge base bulb such as the
168, 175, 198 or a brighter LEDunit.

Pull the old turn
signal bulb straight out of the socket and push in a new amber colored 992 or 7440A bulb straight into the socket.

Insert the socket back into the housing and
rotate it 1/4 turn clockwise to secure it in place.

(If your Prius is equipped with fog lights,
the bulb will be located either below the turn signal bulb or further
inwards near the lower grille area of the bumper. In my experience, to
remove an H16 or 5202 fog light bulb, you have to squeeze together the two
outer release tabs with your thumb and forefinger before pulling it straight
out of the housing.)
